Namiha no Yu uses its own hot spring source, a calcium-sodium chloride spring that gushes out from 800 meters underground at approximately 400 liters per minute. Moving between the indoor bath and the open-air area surrounded by greenery, you can relax in the heart of the city, feeling like you're at a sea-breeze hot spring resort. The spring water has excellent heat retention and moisturizing properties, and is expected to be effective for cuts, burns, and chronic skin diseases.

There are a variety of baths to enjoy, including open-air baths, indoor baths, bedrock baths, and saunas. There are also plenty of facilities, including a restaurant, cafe, and massage parlors.

Shampoos are always available on site, and towels are available for purchase or rental.
